The only exotic pet I've ever owned was a Carolina anole. My mom was never big on small animals as pets. (and even if she didn't mind them, no one in my house knows how to close a door so any small animals I did have was at risk of death by cat) I've got a few ideas for what pets I'm thinking about getting in the future.
I've always wanted a bird, and doing some research, it sounds like the green-cheeked conure might be a good option for me. I want a friendly animal that I could play and interact with, maybe even teach some tricks to. And they're not as high maintenance or long-lived as large parrots, so it wouldn't be too much for me to handle. But I'd probably have to wait until I'm not living in an apartment, since conures can be quite noisy.
I'm also considering sugar gliders, once my lifestyle is appropriate. Unlike the conure, I could keep some in an apartment, and since they're pretty popular as pets, there are plenty of resources to help me out.
I've thought about a fennec fox, but I just don't think I could provide sufficient care. Might be an option for the far future.
